Finally after nearly a year of working, i have finished my masterpiece; I have racked up more geek points by creating a backpack from an old macintosh SE computer c. 1988. I know everyone is saying either A.) why did you destroy a perfectly good macintosh? Or B.) Why didn’t you spend that time making floppy disk plate mail like you promised?

Let’s move on to the actual instructions
